Conclusion
Many organisms are known to adapt to their surroundings, but it is often believed that only the most advanced species can modify their environment to enhance their survival. In reality, this ability is more widespread. For instance, specific types of algae produce a gas that transforms in the atmosphere into nitrate particles. These particles facilitate the condensation of water vapor, leading to cloud formation. In fact, the presence of these particles is crucial for cloud development over large bodies of water. Increased cloud cover results in greater sunlight reflection, causing the Earth to retain less heat. Consequently, algae contribute to a cooler surface temperature on Earth, which in turn benefits the algae. What is the primary conclusion drawn from the statements above?
